- R & A II, Chapter 11 Practice A music teacher hypothesized that singing with hand movements about math will improve the math scores of elementary school children. To test her hypothesis, the teacher obtained permission from 10 parents of Dixie Bee Elementary school children to give their children an extra 30 minutes of singing (about math) instruction at the end of the school day. The 10 children were first given a standard math test by their music teacher. Then they received 30 minutes of singing time with their music teacher, once a week, for 6 weeks. The 30 minute sessions included singing and dancing to songs about math. At the end of the 6 weeks period, the music teacher gave the children the same math test again. Below are the pretest and posttest scores for the 10 children. There were 10 questions on the math test.

A random sample of high school band students was taken and the results are summarized in the table below. Instrument type Band Woodwind Brass Percussion type Concert 31 25 8 Jazz 10 16 10 Marching 65 65 27 To assess whether there is a relationship between band type and instrument type, we conduct an appropriate hypothesis test. Based on the p-value that you calculated in the previous learning check question, which of the following describes the evidence to say that there is a relationship between band type and instrument type? Little evidence Some evidence Strong evidenceIntroductory Statistics 3rd edition - 8.34 p-values For each graph, state whether the shaded area could represent a p-value. Explain why or why not. If yes, state whether the area could represent the p-value for a one-sided or a two-sided alternative hypothesis.

In a research report, it is claimed that mice with an average life span of 32 months, will live to be about 40 months old when 40% of the calories in their food are replaced by vitamins and protein. Is there any reason to believe that μ < 40 if 64 mice that are placed on this diet have an average life span of 38 months with a standard deviation of 5.8 months? Use a P-value in your conclusion with α = 0.05.
